    text
    copied!<p>I'm trying to add some scripting functionality to a Cocoa app that I've written. I've created an <strong>sdef</strong> (Scripting Definition File) for my project. So far I have been successful in accessing object children (elements) with AppleScript but I cannot for the life of me figure out how to call methods (commands).</p> <p>Here is my sdef file.</p> <pre><code>&lt;suite name="mySuite" code="mSUI" description="My Application Suite"&gt; &lt;class name="application" code="capp" description="Top level scripting object."&gt; &lt;cocoa class="NSApplication"/&gt; &lt;!-- I can access these elements fine --&gt; &lt;element description="Test children." type="child" access="r"&gt; &lt;cocoa key="myChildren"/&gt; &lt;/element&gt; &lt;!-- Cannot seem to call this method :( --&gt; &lt;responds-to command="testmethod"&gt; &lt;cocoa method="exposedMethod:"/&gt; &lt;/responds-to&gt; &lt;/class&gt; &lt;class name="child" code="cHIL" description="A Child." plural="children"&gt; &lt;cocoa class="Child"/&gt; &lt;property name="name" code="pnam" description="The child name." type="text" access="r"&gt; &lt;cocoa key="name"/&gt; &lt;/property&gt; &lt;/class&gt; &lt;command name="testmethod" code="tEST" description="Execute the test method" /&gt; &lt;/suite&gt; </code></pre> <p>Here are my controller class implementations (this is the delegate of my application)</p> <p><strong>MyController.h</strong></p> <pre><code>#import &lt;Cocoa/Cocoa.h&gt; @interface MyController : NSObject { NSMutableArray* myChildren; } // Some Methods @end </code></pre> <p><strong>MyController+Scripting.m</strong></p> <pre><code>#import "MyController+Scripting.h" @implementation MyController (Scripting) // This works when I'm accessing the myChildren - (BOOL)application:(NSApplication*)sender delegateHandlesKey:(NSString*)key { NSLog(@"Key = %@", key); return ([key isEqualToString:@"myChildren"]); } // This does NOT work... - (void)exposedMethod:(NSScriptCommand*)command { NSLog(@"Invoked Test Script Method %@", [command description]); } @end </code></pre> <p>Lastly, the AppleScript I am trying is:</p> <pre><code>tell application "MyApplication" testmethod end tell </code></pre> <p>which responds with <code>"AppleScript Error - The variable testmethod is not defined."</code></p> <p>Any ideas what I'm doing wrong here? I feel like I'm missing something simple but my Googling doesn't seem to be turning up anything helpful.</p>
